First of All Bismillah!!
Do you click like button to every video you like? Similarly people dislike, its free! No one will let you have a dislike free video. Sometimes people dislike because there are no dislikes, not because they disliked it but just to put some dislikes. And if you find a famous video which has no dislikes, dislike it.. End of the competition!
Note ⚠️ : YouTube haters can do more than simply ruin your day, they can also cause some serious damage to your brand image#666
